Abstract
A brushless DC motor identification method capable of identifying information on a brushless DC motor, particularly without performing any handshaking, includes supplying an input voltage from an identifier to a brushless DC motor including at least one resistor connected between a power supply line and a GND line, reading a resistance value of at least one resistor in a state where the inverter of the brushless DC motor is off, and identifying information on the brushless DC motor based on the read resistance value.
